Mitsubishi MELSEC System Q User Manual

In the example below the contents of D20 are written to data register D387 when the state of
M110 changes from “0" to ”1".
After this single operation has been performed copying to register D387 stops, even if the
M110 remains set. The signal sequence illustrates this:
Moving 32-bit data
To move 32-bit data just prefix a D to the MOV instruction (DMOV):
When input X1 is on the contents of the data registers D0 and D1 is written to data registers
D40 and D41.(The contents of D0 is copied to D40 and the contents of D1 is copied to D41).
NOTE With GX IEC Developer it is not possible in Ladder Diagram and the IEC instruction list to de
-
fine 32-bit devices as input and output variables directly. These devices must be declared as
Global Variables (see chapter 4.6.2). In this example the identifiers var_D0 and var_D40
were chosen to point to this fact.
